Sending their roots down into bare soil cover crops can increase soil carbon provide slow-release nitrogen
Trees absorb greenhouse gases and carbon emissions. They produce oxygen and perpetuate the water cycle by releasing water vapor into the atmosphere.
Effects of deforestation Forests are complex ecosystems that are important to the carbon and water cycles that sustain life on earth.
Carbon Emissions: Healthy forests help absorb greenhouse gasses and carbon emissions that are caused by human civilization
and contribute to global climate change. Without trees more carbon and greenhouse gasses enter the atmosphere.
To make matters worse trees actually become carbon sources when they are cut burned or otherwise removed. oetropical forests hold more than 210 gigatons of carbon and deforestation represents around 15 percent of greenhouse gas emissions according to the WWF.
Water Cycle: Trees play an important part in the water cycle grounding the water in their roots
and releasing it into the atmosphere. In the Amazon more than half the water in the ecosystem is held within the plants.
Antioxidants help keep other molecules in the body from producing free radicals which can damage cells
These compounds are used also in agricultural fertilizers. That according to several researchers is precisely the problem:
Additionally if these compounds find their way into a stream or lake the fertilizers can kill off fish

The new results published in several studies today (June 3) in the journal Proceedings of the National Academy of Sciences (PNAS) were found by analyzing the fraction of different carbon isotopes or atoms of the same chemical with different molecular weights
The 10 Biggest Mysteries of the First Humans Diet insight Because plants using different methods of photosynthesis to grow absorb different amounts of carbon isotopes the ratio of those isotopes in dental enamel can reveal insights
For instance so called C3 plants absorb more of the heavy isotope carbon-13 into tissue than do C4 or CAM plants.
To analyze what the ancient human ancestors were eating the team analyzed the fraction of different carbon isotopes in teeth from every early human fossil that could be sampled:
Now thanks to stable-isotope analyses we no longer have to guess and the broad pattern of early hominin dietary evolution is established.
#Earthworms Trap Carbon, But Do They Influence Climate Change?(ISNS)--Earthworms have long been the organic gardener's friend.
or burned it releases carbon dioxide. But in a process called stabilization earthworms convert the digestible carbon to a form that stays in the soil.
They re stabilizing it through their fecal material. That type of carbon is more resistant to decay said Deborah Neher of the University of Vermont in Burlington.
 Earthworms ingest the organic matter or litter that lies atop the soil. The litter is ground to a pulp in their gizzard broken down and digested by their gut bacteria
Their excrement also adds physical structure to the soil that holds in the carbon reduces erosion
They measured the carbon dioxide emission carbon mineralization and carbon stabilization of a batch of soil with just microbes and compared that with a batch of soil with microbes and earthworms.
They found that earthworm-stocked soil releases no more carbon dioxide than soil with microbes alone. In fact the earthworms excreted carbon that stuck in the ground rather than releasing it into the air.
Essentially earthworms created a carbon trap. We're losing the litter on the surface of the soil
which has affects on future forest composition but a lot of that may be moving deeper into the soil
and holding the carbon there said Neher. The carbon is just moving into deeper layers in the soil.
Many of the proposed ideas to reduce greenhouse gas emission involve trapping carbon in the soil
but these small creatures have beaten us to it. Other new studies find that the fecal matter of millipedes
and oribatid mites also transform carbon into its more decay resistant form. The second study was conducted over 54 days too short a time to judge the total effect of earthworms on the environment.
 Based on levels of radioactive isotopes or atoms of the same elements with different molecular weights the team estimated that the site was occupied almost continuously between 9800 and 12000 years ago.

Roman locavores To determine diets from the Roman skeletons the researchers analyzed the bones for isotopes of carbon and nitrogen.
Isotopes are atoms of an element with different numbers of neutrons and are incorporated into the body from food.
Such isotopes of carbon can tell researchers which types of plants people consumed. Grasses such as wheat and barley are called C3 plants;
The differences in photosynthesis create different ratios of carbon isotopes preserved in the bones of the people who ate the plants.
Nitrogen isotopes on the other hand give insight into the kinds of protein sources people ate. We found that people were eating very different things Killgrove said.
One man whose isotope ratios showed him to be a major millet consumer was likely an immigrant later research revealed.

#Some Weight Loss Supplements Contain Amphetamine-Like Compound Some popular weight-loss supplements contain a synthetic compound that is chemically similar to the drug amphetamine according to a new study by researchers at the Food and Drug Administration.
But 9 of the 21 dietary supplements tested were found to have an unnatural compound called beta-methylphenethylamine
This compound has never before been tested in people although animal studies suggest it may behave similarly to amphetamine
For example nearly all of the supplements had high levels of a compound called phenethylamine but this compound is found at very low levels in the plant itself.
Given the low natural abundance of phenethylamine in the plant materials it appears nearly impossible to achieve the amounts of phenethylamine found in the dietary supplements by formulating them with plant material
Observations of the system revealed a dust trap of millimeter-size grains on one side of the star with smaller micrometer-size particles spread evenly throughout the disc.
The particles astronomers said could eventually clump into a comet factory producing kilometer-size rocks such as those found in the Kuiper Belt outside Neptune's orbit.
Due to this pressure gradient gas and small micrometer-size particles have slightly slower orbital velocities around the star.
When the millimeter-size bits grow they begin to experience friction with gas and smaller particles.
Eventually the larger particles slow down themselves. When the friction drops their speed below a certain threshold they drift toward the star
which make up about 10 percent of the Earth's land surface and more than 30 percent of its terrestrial carbon stock.
The results are particularly striking given that wildfires release the forests'stored carbon into the atmosphere potentially exacerbating climate change.
They also spew huge amounts of carbon and asthma-inducing particulate matter into the air a big fire is like setting a coal-fired power plant in the middle of a forest.
